Patented Apr. 11, 1944 UNITED STATES PATENT OFFICE p THERAPEUTIC DEVICE Samuel Zichlin, Brooklyn, N. Y. Application May 23, 1942, SerialNo.y44g1,232 I A 6 Claims. (o1.f12s-4o1) This invention relates to new and useful improvementsinatherapeutic device. I v 1 More particularly, the invention proposes the construction of a device as mentioned which is adapted to be used in gynecological and proctological conditions, in the ears, andother orifices and cavities of the body, and on parts of the body. Of course, it must be realized that for different purposes the therapeutic device must be-ofjdifferent sizes and contours. and cavities it may be cylindrical. For use on the neck, jaw, abdomen and other regions it should b flat, or flat and curved. It may also be used in other shapes.

More particularly, it is proposed that the therapeutic device be in the natureof a hydro-jacket for engaging in the body orifices and cavities mentioned, or against parts of the body, and be provided with an inlet and outlet for hydraulic fluids, and certain internal guides be provided for.

forming a continuous passage for the hydraulic fluids. It is proposed that the hydraulic fluids be supplied under pressure, preferably by a pumping system, and be supplied at selected temperatures. proposed that an electrode-unit be mounted within the hydro-jacket for heatcontrol and for the control of certain rays. a

The therapeutic device is in the nature of an orificial dilator to dilate, cool, heat, and in other:

ways enhance the therapeutic effect of'infr'a-red, quartz, short and long wave diathermy, etcijby thermic control of the hydraulic fluid which permits use of higher potentials and therefore permits a greater elaboration of radiations and emait may be controlled as to temperature and pressure by a water pump, driven electrically, or 'manually, and thermostatically controlled. 1 Suitable meters may also be provided for constant reading of changing temperatures during or after treatment.

This new therapeutic device-will eliminate or greatly reduce burns now generally experienced by patients usin therapeutic devices. The construction of the hydro-jacket of Lucite or other plastics will prevent cuts from glass electrodes For certain orifices In another form of the invention it is due'to accidental breakage while under treatment. r i

For further comprehension of this invention, and of the objects and advantages thereof, reference will be had to the following description andaccompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The therapeutic device, in accordance with the form of the invention illustrated in Figs 1 and 2,

includes 'ahydro-jacket Ii] preferably made of Lucite'or other transparent or translucent plastic material, or pyrex or other glasses. This jacket I ll may be made of a size and shape to engage body' orifices and cavities or to engage against parts of the body. The jacket I0 is provided with a valve controlled inlet 1 l and a valve control discharge l2. A guide vane I3 is located within the jacket l0 forming a continuous passage for hydraulic fluid from the inlet ll to the --acrossthe jacket 10 and is removably mounted on dove-tailed tracks l6 formed'alongthe inner sides of the jacket. The guide vane l3 extends from the back of the jacket to a point I! spaced inwards from the front of the jacket. With this arrangement the hydraulic liquid may enter the inlet pass along one side of the jacket H] and around the end ll of the guide vane l3 and back along the other side of the jacket, and finally discharge from the outlet I2. The hydraulic fluid supplied to the jacket Ill may be supplied under preselected speeds, pressures and temperatures for the proper treatment prescribed for a patient.

In Figs. 3-8 inclusive a modified form of the invention has been disclosed which distinguishes from the prior form in the fact that the guide vane l3 has been removed and in its place an electrode unit 2|] and guide vanes 2| substituted. The electrode unit 20 is in the nature of a glass vacuum tube through which an electric element 22 passes. This electric element connects with terminals 23 and 24 at the outer end of the electrode unit. The electrode unit 20 is provided with tracks 25 along its sides. The guide'vanes 2| are mounted between the tracks 25 and the tracks l6 of the jacket l0. Each guide vane 2| comprises an elastic band 26 having dove-tailed strips 21 mounted along its edges. These dovetailed strips 21 are adapted to engage complementary grooves formed along the tracks I6 and 25.

The electrode unit 20 extends to a point |'I' spaced slightly inwards from the front end of the jacket Ill. The guide vanes 2| also extend to said points H. The electrode unit 20 is adjustably mounted so that it may be moved towards one side or the other side of the jacket ID. This shift will change the relative sizes of different portions of the continuous passage within the jacket. For example, in Fig. 6 the electrode unit 2|] is shown centrally located. Then the passage 28 and 29 to the'sides thereof are identical. However, Fig. 8 illustrates the electrode unit 20 in a shifted condition. The passage 28 is then much smaller than the passage 29'. This change will cause the hydraulic fluid to flow rapidly through the passage 28 and slower through the passage 29'. Thus the opposite sides of the jacket are being cooled or heated to difierent degrees.

The electrode unit 20 extends through an elongated slot 30 formed in a washer 3| which is mounted across the back end of the jacket II]. This washer 3| is held in position by a cap 32 threadedly engaged on the back end ofv the jacket Ill. The back of the electrode unit 28 is provided with a tubular gasket 33 inthe nature of a bushing. Another gasket 34 is mounted on the tubular gasket 33 and projects at right angles therefrom. The gaskets 3'3 and 34 are replaceable. Normally the gasket 34 comes quite large and may be cut down to a proper size so as to support the electrode unit 20 in a selected position in the elongated slot 30. The gasket. 34 is clamped in position by a ring 35 threadedly engaged on the cap 32. However, before the ring 35 is placed in position it is necessary that the gaskets be painted with gasket cement to insure a water tight connection- The operation of this form of the invention is similar to the prior form but distinguishes in the fact that in addition to temperature control caused by the controlled hydraulic fluids passed through the jacket, it is possible to. shift the electrode unit foradditional temperature control and ray control. When desired the ring 35 may be unscrewed and the electrode unit removed. The gaskets 33 and 34 may be replaced with new gaskets and the electrode unit replaced in a selected position within the jacket ID. This arrangement permits differential temperatures at the sides of the jacket H] for certain treatments.

In Fig. 9 still another form of the invention is disclosed which is similar to the form shown in Figs. 3-8 inclusive, distinguishing merely in the fact that the therapeutic device is provided with a jacket l0 having a relatively flat front end. While this particular shape is shown it should be borne in mind that other shapes may be utilized.

In Fig. 10, the electrode unit or element 2|] is 'shown to be externally located from the fluid jacket I0", so that in certain cases it may be more conveniently used for external applications.

It is to be understood that the shape, size and material used for the fluid jacket l0 may be changed as desired to conform with the contour of the particular anatomical structure treated. The electrode element 2|] may be made of any shape or design, of any desired size and strength, and attached internally or externally of the fluid jacket in any convenient manner.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of, the invention as defined in the appended claims.
